Hi guys, I’m new to this. I have a rzr 900s and as I was taking the belt box off to seal it up one day, I noticed that there was a lot of oil residue on the motor. So when I had everything off, I cranked the bike up to see if oil was leaking somewhere. Of course it was, it was coming out of the crankcase seal( the one that rides on the shaft). My question is this. Has anyone changed this seal without cracking the case open? I know the stock seal is has a lip on it, but I was wondering if it can be changed and perform like it is suppose to, by maybe grinding off the lip of my new seal( I bought two new seals) and trying it that way. Any help will be greatly appreciated.
